Placenta expulsion (157.20 minutes), uterine involution (30.60 day), onset of 1 st heat (40.20 day), calving interval (456.00 day), DO (182.80 day) and NSC (2.60 serv.) decreased (P<0.05) in G4 as compared to other groups. Concentration of T 3, E 2 and iodine during pre-and post-partum increased (P<0.05) in G4 as compared to the other groups. She camels in G4 showed the highest (P<0.05) DMY and TMY (4.20 kg) and the longest (P<0.05) lactation period (350.20 day). Results revealed that immunoglobulin concentration in colostrums was higher (P<0.05) in G4 as compared to G1, G2 and G3. After calving, live body weight (LBW) of calves was recorded and average daily and total gain was calculated. Post-partum placenta expulsion, uterine involution, onset of 1 st heat, calving interval, days open (DO), number of services/conception (NSC) and conception rate (CR) were recorded. Concentration of immunoglobulin's was determined only in colostrum, Pre-partum and post-partum blood samples were taken for determination of total protein, globulin, glucose, total cholesterol (CHO), triglycerides, progesterone (P 4), estradiol-17ß (E 2) and iodine concentrations in blood plasma. Milk composition and milk iodine were determined. Daily (DMY) and total (TMY) milk yield, and lactation period length were recorded. Animals in the 1 st group (G1) were fed a control diet, while those in G2, G3 and G4 were fed the control diet supplemented with 0.5, 0.8 and 1.0 mg potassium iodide/kg DM intake /h/d, respectively. Animals were divided into four similar groups (5 in each). Twenty pregnant Maghrebian she-camels (3-5 parities) with live body weight ranging between 430 and 450 kg were used in this study. This study aimed to evaluate the effect of different levels of iodine supplementation during the period extended approximately twelve months (three months before and nine months after parturition) on immunity and performance of calves, and milk yield, milk composition, some blood parameters and reproductive performance of lactating she-camels. ![]() Conclusion: The results showed that nutrient supplementation in terms of high protein concentrate, ASMM and injection of sustained release micro-minerals (Se, Zn, Cu, and Mn) during transition period minutely altered the plasma steroid hormones and blood metabolites though it significantly improved the postpartum reproductive performance in buffaloes under field conditions. Thus, the postpartum reproductive performance was significantly improved in treated than control groups and subgroups. The micro-minerals injection apparently and/ or significantly improved all these traits in both the groups. In treatment group, the period for involution of uterus was significantly shorter (29.39☐.50 vs. The micro-minerals injection appreciably reduced the incidence of RFMs and significantly (p<0.05) reduced the placental expulsion time over non-injected controls. ![]() Results: The mean plasma progesterone concentrations in all groups declined significantly (p0.05). The puerperal events and postpartum fertility were monitored through history and by fortnightly palpation per rectum till day 45 and then again at 120 days postpartum for both the groups and subgroups. Blood sampling was done on days −60, −30, −15, 0, 15, 30, 45, and 60 peripartum for estimation of plasma progesterone and estradiol by standard RIA techniques and other metabolites using assay kits on biochemistry analyzer. Further, 15 buffaloes, each of control and treatment group, were injected parentrally (deep i/m) with 5 ml of micro-minerals (each ml containing Se, Zn, Cu and Mn at 5, 40, 15 and 10 mg, respectively), twice 2 months before and on the day of calving, keeping rest of the animals (control, n=30 and treatment, n=25) as controls. The buffaloes of treatment group (n=40), in addition to farmers feeding schedule/control, received daily 1.5 kg compound concentrate mixture (22% CP) and 50 g of chelated ASMM for 2 months each pre-and post-partum. Material and Methods: A total of 85 advanced pregnant (~8 months) pluriparous buffaloes selected at farmers' doorstep in three tribal villages of Middle Gujarat were randomly divided into two groups, viz., control (n=45) and nutrients treatment (40). ![]() Aim: The aim of this study was to evaluate the influence of peripartum protein and minerals supplementation on plasma profile of steroid hormones, metabolites, and fertility in rural buffaloes.
